So the two equations should be set up equal to each other.
1x + 8 = 2x - 4
now subtract 1x to 2x
8 = x - 4
now add 4 to 8
12 = x
to check you can plug it into x and see if they are both equal
Based on the formula given for the model of the average cost of tuition and fees, the average cost of tuition in 2010 was $25,858.
<h3>What was the average cost of tuition at private colleges in 2010?</h3>
The base year is 2000 and x denotes the number of years after 2000.
The value of x for 2010 is therefore:
= 2010 - 2000
= 10 years
The average cost of tuition in 2010 is therefore:
= 26 (10)² + 814(10) + 15,118
= 2,600 + 8,140 + 15,118
= $25,858
